The First Quarter Moon was over to the East more than the flare was supposed to be and was easily visible unobstructed in the growing twilight even though it was lower in the sky.

The humidity has dropped since dinnertime, but it is still close out. I can see some cloud again but can’t be sure how much there really is. I did see the Big Dipper (a.k.a., the Plough) so the sky is clear at least there.

CalSky says this was Iridium 91 and is a spare satellite so the brightness estimate may be unreliable.

This was another night when there was a string of closely spaced flares that were supposed to have moved to the right and down with time.

Observing LocationMO
I had gone up to PSC and found a place where I could see the chunk of sky I needed between the trees and the buildings and was sitting there reading when one of the rent-a-cops came by and told me that it was after 2300 EDT and I had to leave. I checked to make sure she was serious and she was so I packed up and moved outside of the circle onto the sidewalk that provides access to eight apartment buildings and was reading there for a short while when another rent-a-cop came by with the same demand. It seems that they are classifying the sidewalks part of the “park” and are denying access between 2300 EDT and 0600 EDT. This is crazy since it means that anyone who is out late at night can’t get to their apartment without breaking the “law” This will affect over 500 families. I hope this is a temporary thing in anticipation of the 4th of July since there is no reasoning with the rent-a-cops. I went up to the oval, which is just as much a “park” and was not hastled at all there.

I can’t see much in the way of clouds but the only star I can see is Arcturus. I think Spica should be visible between the buildings but I don’t see it.
